An ion is an atom which has more or less electrons than protons. If it has more electrons it's a negative ion, and if it has less electrons it's a positive ion. An atom loses or gets electrons in reactions with other elements.
Removal of an electron from an atom leaves a positively charged ion.

When an electron is removed from an atom, it is considered to be ionized. This results in the formation of a positively charged ion known as a cation, while the atom itself becomes positively charged.
An ion is a single atom that carries a positive or negative charge due to gaining or losing valence electrons. The atom becomes an ion when it has an unequal number of protons and electrons.
An ion is an atom with a positive or negative charge.
Removal of an electron from an atom leaves a positively charged ion.
An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.
When electron transfer results in an ion larger than the original atom, it is likely that an anion has formed. This occurs when an atom gains electrons and becomes negatively charged. The additional electrons increase the electron cloud size, making the ion larger than the original atom.

A calcium ion (Ca2+) loses two electrons from an atom to achieve a stable octet electron configuration. This results in a +2 charge on the calcium ion.
Sodium loses its one valence electron to become Na+
an ion
A sodium atom would lose a electron so it would become a Na+ ion
The fluorine atom can become an ion by gaining one electron to achieve a stable electron configuration of 8 electrons in its outer shell. This results in the formation of a negatively charged ion known as fluoride ion (F^-).
Ionic bonding results from the transfer of electrons between a metal and a nonmetal atom. The metal atom loses electrons to form a positive ion, while the nonmetal atom gains electrons to form a negative ion. The opposite charges attract, creating the ionic bond.
